TRANSMISSION REMOVAL AND REPLACEMENT

I have found a 1990 Dodge Daytona ES in great condition except for the transmission which begins to slip when going over 40mph. It has an 4spd automatic (overdrive) with a 3.0 V6. This transmission is easy to find, but want to know if it is worth paying someone 350.00 to install it or do it myself. I have removed engine/transmission and replaced in my ElCamino, but never done much with a front-wheel drive car. How much work is it to remove and replace this particular transmission? Any other sources to get info from that you recommend? Books, DVD's, etc.
